To all whoml it may concern.'

Bc it known that I, Leno! S. Prours, a citizeri of the United States, residing at Canton, county of'Stark, und State oi Ohio. have invented certain new and useful Improvements in Pasteurizing Appamtus for the following is a full, clear. and exact description of the same, reference being had to the annexed drawing, making a part. of this specification, and to the numerals2 The steam pipe'i leads to nnyusource of supply to which pipeis attached in the usual manner the down steam pipe 24, whichown steam pipe entends through the stand pipe 22 and into the upper chamber and its lower end provided with the steam heater 25, which stesi"` heater is for the purpose of heating the water contained n'n the upper chamber.' From the steam 'pipe 23 leads the down pipe 26, which down pipe ex'- [lends through the ,pipe 19. and into the coupling 18 and figures of reference marked thereon. por the lower rotating chamber as the case may be and The present invention has relation to pasteurizing in the different parts and combination of parts hereinafter described and particularly pointed out in the claims.

In the drawings-Figure 1- is a. vertical section showng the different parts 4properly arranged with reference to cach other. Fig. 2 is 'n longitudinal section of thc inspirator. Fig. Biss horizontal section ofthe heater. l? ig. 4 is a view on the line;4-4 looking down. Fig. `5 is u. view on the line 5 5, `Fig. l, except the In the accompanying drawing, 1 represents the base which is designed to support and hold the various parts in proper position and may be securely fixed by means of suitable bolts 2, The power shaft 3 is properly juurnaled in the base l in the usual manner, and should be provided with the tight and loose pulleys 4 sind 5, which are driven in the usual manner by a belt. To the shaft 3 yis attached the miter gear 6, which gear ne-ing securely attached to the hollow shaft 8. to which shaft is attached the hub 9, said hub being preferably 10, to which liquid retaining chamber is attached .the pusteurizing plate or disk l1. Directly above the pasteurizing plate ll is located the pasteurizing plate taining chamber 13.'

For the purpose of supporting the upper liquid retaining chaudiere-using 13 and the different partscoib net-led thereto and carried thereby. said casing is provided with the lateral arms 14, which lateral arms are held by means of thc screw threaded nuts 15. which nuts are locutedlupon the screw threaded rods 16: siid. rods heilig supported by means of the arms 17.. and the arms 17 connected to the hase l or its equivalent. To the top of the hollow shaft 8 is attached the coupling 18, which coupling extends through the lower chamber. and to thetop of the coupling is attached the pipe 19 said parts being lot-ated and ananged substantially as shown in Fig. 1. To the upper liquid retaining cham'. ber 13 are attached the stand pipes 21 and 22, which"V Lthe lower end of` said pipe provided with s. steam heater' 27, which steam heater is substantially the same ss the heater 25 and is for the purpose of heating the liquid in the lower chamber. lt will be understood that the coupling 18 should be provided with suitable paages 28, which are for the purpose of producing what might be termed a continuous chamber as between the coupling 18. and the lower casing 10 For the purpose of regulating the flow of steam inthe down pipe 24 and 26 the valves 29 and SOare provided which valves are of the usual construction. From the steam pipe 23 leads the pipe 31, to which pipe is conthe pipes 33 and 3G the pipe 33leading into the pipe 19 and the pipe 34 into the stand pipe 22, said parts being connected together substantially as shown in Eh'g. l. lt will be understood that the liquid contained in the upper and lower chambers lcan be heated by means of the steam forced through the pipes 24 and 26 and caused to circulate from the lower chamber to the upper by paming upward first through the pipe 33, the injector 32 and the pipe {i4-and as the liquid rises in the stand pipe liquid comes above the level in the stand pipe 2l it will pass through the pipe 35 and into the lower chamber from which it was taken thereby producing acontinucus circulation thereby causing the temperature to be the 'same in both the upper and lowerfchambers and of course heating the upper and lower pasteurizing plates alike, which is a very important feature in the proper pasteur-ization of liquids, owing to the fact that where dierent degrees of temperature are liable to take place as between two pasteurizing plates, the liquid isliable to either become overheated or under heated; but by my peculiar arrangement this di `culty is entirely avoided. The liquid designed to be pasteurized is fed into what might be tznned the hopper 36 paing downward and between the two par teurizing plates, 11 and 12, which liquid is forced outward toward the peripheries of the pasteurizing plata and delivered between the cooling plates 37 and 37* the purpose of changing the space as between the pustand pipes are for the purpose hereinafter described.

nected the injector 32, and to said injector isattached 22 it finds its `level in the stand pipe 21, and when the from whence it is conveyed to the trough 38 and from the trough conveyed to any suitable receptacle. For

plates 11 and 12, and thereby increasing and 110 decreasing the stratum of liquid. the nuns l arc each provided with the sprockets .'59 over and upon which sprocket are located the sprocket chain 40.

, lt will be understood that, by rotating the sprockets L' 5 39 will also rotate the nuts 15, thereby elevating or lowering said nuts upon the rods 16, reference being had to the direction of rotation, it of course being understood that the arms 14 together with Ithe upper casing and the different parte carried thereby, will be tl moved upward as the nula 15 are moved upward and will go downward by gravity when the nuts 15 are lowered. i Forthe purpose of properly cooling the plate 37 the outer face of said plate has attached thereto a series of 15' helical @enges 41, which helical flanges are spaced r from each other and connected together arid to the :plate 37 by means of solder or ita equivalent.A The cooling liquid ia fed from any source of supply through the pipe 42 and removed through the pipo 43.

i For the purpose of closing tae bottom or lower end of the hollow shaft the cap 44 is provided, und is removably attached to the bottom orlonzr end of Suid hello-w limit. When it is dciredv to remove the liquid .fn-m

. the lower chamber the cap 44 is .removed which ullows the liquid to pues through the passages 45. said passages oommuncating with the shaft 8 as illustrated in Fig. l. For the purpe of reducing friction the hu b 9 is carried f upon the anti-friction balls 46, said anti-friexitm hulls i being located as illustrated in Figi. B0- For the purpoee of supporting the pipes 2li and 33 the kbrace 50 is provided, 'which bruco i attached to the Irma 14 or their equivalents. For the purpose of properly cooling the plate 37" thc inner face of raid plato )m5 attached tht-reto a series of S15-helical flanges 47 which are eou,-rr|u-ted iu substan- -vtially the sume manner :1s thfl helical flanges 4l Tlvl cooling plate 37 is curved at iter top or upper end 11nd is w curved for the purpose of guiding.y th(- liquid he tween the cooling platos'.
